Description détaillée
Introduction: Low-flow anesthesia techniques have regained popularity in recent years with the development of low solubility volatile agents such as sevoflurane and desflurane, and modern anesthesia devices. Reducing the flow of fresh gas as much as possible will reduce the amount of volatile agent used, thus preventing air pollution, providing lower costs, and also preserving heat and moisture in the respiratory tract by using rebreathing systems. Laparoscopic surgery is superior to open surgical techniques due to its minimally invasive nature, less postoperative pain, less incidence of wound infections, shortening the hospitalization, and allowing patients to return to their normal lives sooner after the operation.
Our aim is to investigate the effect of minimal flow anesthesia with sevoflurane on hemodynamics and arterial blood gas parameters in laparoscopic cholecystectomy operations.
Material and Method: Seventy patients with ASA (American Society of Anesthesiologists) class I-II between the ages of 18-65 undergoing elective laparoscopic cholecystectomy were included in the study. After the patients were randomly selected by computer, they were divided into two equal groups as Group M (minimal flow anesthesia group) with fresh gas flow 0,5 L.min-1 and Group C (high flow anesthesia/ control group) with fresh gas flow 4 L.min-1. In both groups. Demographic data, duration of anesthesia, operation times, recovery times, hemodynamic parameters and arterial blood gas parameters of all patients were recorded. The patient data collected in both groups were compared statistically.

Comparateur actif: Group M
Group M is minimal flow anesthesia group with fresh gas flow 0,5 L.min-1.
Thirty five patients with ASA class I-II and between the ages of 18-65 undergoing elective laparoscopic cholecystectomy will be included.
These patients were planned to be administered sevoflurane anesthesia with 0,5 L.min-1 flow under general anesthesia.
|
The sevoflurane dose differed in both groups in relation to the fresh gas flow.
Since the fresh gas flow is less in group M, the concentration of sevoflurane consumed by the patient at the end of the case will be less.

Comparateur actif: Group H
Group H is high flow anesthesia group with fresh gas flow 4 L.min-1.
Thirty five patients with ASA class I-II and between the ages of 18-65 undergoing elective laparoscopic cholecystectomy will be included.
These patients were planned to be administered sevoflurane anesthesia with 4 L.min-1 flow under general anesthesia.
|
The sevoflurane dose differed in both groups in relation to the fresh gas flow.
Since the fresh gas flow is less in group M, the concentration of sevoflurane consumed by the patient at the end of the case will be less.
